So, while it may not be the smallest, I thought I\'d add this one to the list because it\'s (slightly) different from anyone elses.* Originally had 3 landing gear. Dropped them the moment i was airborne (the small drop at the end of the runway is what allowed me to get into the air *cough*) Mini-Jet, powered by RCS thrusters! A micro-jet with micro-engines! All stock parts. Only 1 RCS tank, noticable by the fact it took most the fuel just to get to the end of the runway, and into the air :| It\'s not exactly classified as a \'long-range\' aircraft. didn\'t seem *too* hard to fly once in the air. the main difficulty for me is that you cannot let go of the Thrust-forward button. Throttle obviously having no effect here. *: it\'s 5 am, and there\'s a good chance i missed one, two, all of the posts in this thread XD but apparently awake enough to design a spaceplane... But I guess it\'s never a bad time to make space vehicles on Kerbin.
